This crank arm came from a mid 80s Columbia mountain bike and is in good working condition. There is some grime on the chainrings but it doesn't seem like they are worn out. I don't have the other crank arm unfortunately, the thread was damaged and I couldn't get it off the bike. The BB interface is a square taper, and the chainrings appear to be riveted, not bolted. VERY heavy, this thing is steel and weighs over 2lb Feel free to ask any additional questions via message.
